I also tried to build a computer and got to some point, but the busyness of life caused it to be delayed for a long time.
Anyway, for multiplication, you need to build a circuit that first receives a number as the first number and subtracts 0.1 from it (this way you can multiply up to 10 digits, but if you use 0.01, up to 100 digits, etc.) Then, each time it subtracts, it stores it in memory and simultaneously adds the second digit to the memory number.(The number in the second memory is initially 0, but gradually increases, for example, 0>2>4>6) and do this again, read the number from the first memory again, subtract 0.1, and do all these operations until nothing remains of the first digit.
I've tested this before and I think... yes, it worked. I had the display connected directly to it, so I could see how it added up the numbers step by step, and I have to say, it's really interesting to watch your own calculator think!
